Today’s outcomes
- Explain wireframing tools and prototype exercise in the context of prototyping and testing.
- Decide a product decision using the source outcome rather than intuition alone.
- Produce a reusable section of a prototype test card.

Core lesson
Make the choice inspectable
Wireframing tools and prototype exercise matters when it changes a real allocation of attention, money, time, or delivery capacity. A prototype is a question made tangible at the cheapest useful fidelity.
Start by naming the decision and the uncertainty around it. Separate evidence from assumptions, compare at least one alternative, and state what would make you revise the choice.
The source outcome for today is: List the various types of prototypes.
What decision will wireframing tools and prototype exercise improve, what evidence is sufficient for that decision, and what is the cost of being wrong?
Worked example
Wireframing tools and prototype exercise in practice
For a remote physiotherapy service, the product manager must decide a choice about wireframing tools and prototype exercise. The team records the target user and outcome, the evidence currently available, the strongest alternative, and the next reversible test. The recommendation is written as a choice with a reason—not as a list of features.
Do the work · 20 minutes
Turn the idea into a decision
- Choose a product you know and write the specific decision that wireframing tools and prototype exercise should support.
- List two pieces of evidence, two assumptions, and one credible alternative.
- Make a recommendation in three sentences and add one condition that would change it.

Answer before opening
What is the decision at the centre of wireframing tools and prototype exercise?
A good answer names an accountable choice, not merely an activity or output.
How should evidence and assumptions be separated?
Label observed facts, interpretations, and untested beliefs explicitly so the next learning step is visible.
What makes the recommendation revisable?
It includes a trigger, threshold, or new evidence that would justify changing course.
What should the portfolio artefact communicate?
The context, considered alternatives, chosen direction, rationale, evidence, and remaining risk.
